To all whom it may concern:

Be it known that I, EDWARD C. ANGELL, citizen of the United States, residing at New York, in the county ofNew York and Stateof New York, have invented certain new and useful Improvements in Devices for Displaying Advertisements; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to devices for displaying advertisements, and it consists in the provision of novel means whereby a sheet or apron of flexible material on which advertisements may-be printed or mounted is caused to travel in a given direction with "an intermittent movement, and in the provision of a certain novel construction by means of which the direction of travel of the .sheet is automatically reversed at the proper time.

In the accompanying drawings forming part of this application, Figure 1 is a plan view. of the device: Fig. 2 is a view taken on line 22 of Fig. 1 looking in the direction of the arrow and showing certain of the shafts operated through the medium of the gear trains: Fig. 3 is a detail view showing the mechanism through the operation of which the clutchesare thrown out of engagement, this view being taken on the line 3-3 of Fig. 1. Fig. 4is a detail view of one of the clutches: Fig. 5 shows a worm wheel and worm shaft forming a part of the driving mechanism.

Referring to the drawings in detail, 1 indicates the sheet or apron on which the advertisements may be printed or on which advertising posters may be mounted. The

apron is connected at one end to a roller 2 and at the opposite end to a roller 3, the former being mounted on an axle 4 and the latter'on an axle 5 properly journaled in the cross-piece 17 in the casing 6. Suitable guide rollers 7 and 8 support the apron at points adjacent to the rollers 2 and 3. The axle 4 carries the gear wheel 9 and the corresponding axle a gear wheel 10, these gears meshing respectively with gears lland 12, the first of which is rigidly mounted on shaft 13 and the second on shaft 14. Shaft 13 is supported in bearings carried by brackets 15 and 16 secured to the cross piece 17, shaft 14 being mounted in a similar manner. On the central portion of the cross piece 17 is mounted a U-shaped bracket 18 provided with hearings, in which a shaft 19 connected with this collar which is flanged,

ag shown in the drawing, are levers 25 and 2 mounted respectively at the points 27 and 28, such levers serving to control the movement of the apron.

The driving mechanism is shown in the lower part of Fig. 1, 28, indicating a motor from the shaft 29 of which a gear 30 is driven, this gear imparting motion to gear 31 through gears 32 and 33 to the gear 34 mounted on shaft 35. Gear 34 imparts motion to gear 43 onshaft- 44 and through gear 45 to gear 46 and the bevel gears 47 and 48. Gear 48 drives a worm shaft 49 meshing with a worm Wheel 50 carried by shaft 51, such shaft 51 driving crown wheel 36. Supporting brackets 39 and 40 carry sliding bars 41 and 42 having ratchet teeth on their adjacent ends for the purpose of engaging the teeth on the crown wheel 36, one side of which is provided with ratchet teeth 37, extending one-half of the distance around its circumference, and the other side with ratchet teeth 38 covering the remainder of the circumference of the wheel. Shaft 35 carries a sprocket wheel 35 driving a chain 53, which in turn drives sprocket wheel 22 on shaft 19. Itwill thus be seen that the motor drives a chain of gears which com-' municate power directly to shaft 19 which is thereby continuously operated. The position of the clutch collars carried by shafts 13 and 14 control the direction of movement of the apron. The lower end of lever 25 is slotted and engages a projection 54 on bar 41 whereby the operation of bar 41 will throw lever 25 and the connecting clutch member 24. The corresponding bar 42 on the opposite side of the crown wheel performs a similar function with reference to connecting lever 42*.

The apron 1 carries a series of cleats 55 which are spaced apart and provide a suitable advertising area between each pair. These cleats project slightly beyond the edge of the apron, as shown at 56, for the purpose of engaging the ends of levers 57.

Levers 26 and 26 'are connected with the levers 57 mounted at points near the respective winding rollers, one. arm of such levers 57 being engaged by the projections 56 of cleats 55. Itwill be observed that,

when the apron 1 comes into a given position one of the cleats will strike one arm of ,lever 57, will throw connecting rod 58, opershaft 13.

. pose a given advertising space. The numberof teeth on eachside of wheel 36 corresponds with the number of advertising spaces. When the apron has been fully wound upon one of the rollers, all of the teeth 37 on one side of the crown wheel have performed their function, having thrown the clutch members into cooperation a given number of times and thereby displayed all of the advertisements on the apron. The teeth 38 on the opposite side of the crown wheel will then come into play and act in a similar manner on bar 42, lever42, and clutch 23, thus reversing the direction-of travel of the apron. I

The crown wheel constitutes acontrolling member, and this member cooperating with certain mechanism intermediate of said member and the traveling member-or apron causes the intermittent movement of the latter and the automatic reversal thereofJ The intermediate mechanism referred to ineludes the levers 25 and 26, the clutch member connected therewith, the reciprocating bar connected with lever 25, and the devices carried by" the traveling member or apron and operating lever 26 through themedium of members 57 and 58.

What I claim is:

1. In a display apparatus, a traveling member, a plurality of winding rollers therefor, a driving mechanism for said rollers, a controlling member, intermediate mechanism connecting the controlling member with the traveling member and having 'connection with the driving mechanism, and means'carried by the controlling member and cooperating with said intermediate mechanism for causing the intermittent movement of the traveling member and the reversal-of the direction of movement.
